Estrogens (AmE) or oestrogens (BE) are a group of compounds named for their importance in the estrous cycle of humans and other animals. They are the primary female sex hormones. Natural estrogens are steroid hormones, while some synthetic ones are non-steroidal. Their name comes from the Greek words estrus = sexual desire + gen = to generate.
Very feminine. Alternatively see testosterone.
